our city sewer people are very tight lips about letting people dump here. the guy who runs the place told me that there are a lot of people our there who do not have the faintest clue what non potable water means. seems the city here only has non potable water faucets near the dump station and he has seen people filling up there fresh water tanks with the water. and he has had to stop them many times and then they get mad at him for not telling them the water is not safe. he points to the big sign he has and they just scratch their heads like so what's that mean. it is not just here in my town, I saw it with my own eyes at an Oregon state park one year. big sign "Non potable water", and a MH guy was filling his tank with it. My friend went over to tell him and he got a mind your own business talk. so my friend told him enjoy your diarrhea trip.
